Now as fish is the object which is offered, (the accusative/direct object part of this construction) could I not say... fiskur er boðinn upp á hér? I've been informed this could be a wierd example due to the inherent preposition in the verb but if any one can think of any other examples which could be constructed in all the categories listed.. i.e. (Active, passive, impersonal) but passive for the direct object and not the indirect object where þér is used.

I know the passive for verbs that govern the accusative are as such... Hún var slegin!

And for dative are as such.... Henni var gefið (eitthvað)

But as this bjóða governs both the accusative as the direct object and the dative as the indirect, surely that means there are two possible passive forms, one which denotes who is offered as the topic (dative) and one that says what is offered as the topic (accusative). I am asking about this second one, which logic (atleast my logic) would dictate is written as fiskur er boðinn upp á...
